Quizplus · Accepted Answer

Serial dilution involves diluting a sample multiple times to reduce the number of cells or organisms present. Pour plates involve combining the diluted sample with agar and allowing it to solidify, which will allow for the growth of individual colonies. By using a series of dilutions and pour plates, it is possible to isolate pure cultures of microorganisms.
